Standpipe for a warewashing machine

Abstract

A standpipe for a warewashing machine defining a drain aperture, the standpipe having an elongated tubular body having an open top end defined by a top edge and an open bottom end, and a cover portion including a base wall and a continuous sidewall extending downwardly from an outer perimeter of the base wall, wherein a bottom edge of the sidewall of the cover portion extends downwardly beyond the top edge of the elongated body.

The invention claimed is: 
     
       1. A standpipe for a warewashing machine defining a drain aperture, the standpipe comprising:
 an elongated tubular body having an open top end defined by a top edge and an open bottom end; and 
 a cover portion including a base wall and a continuous sidewall extending downwardly from an outer perimeter of the base wall, 
 wherein the cover portion axially overlaps the top end of the elongated tubular body such that a bottom edge of the sidewall of the cover portion extends downwardly beyond the top edge of the elongated body and defines a gap between the sidewall of the cover portion and the elongated tubular body through which fluid can flow from an exterior of the cover portion into the top end of the elongated tubular body. 
 
     
     
       2. The standpipe of  claim 1 , wherein the sidewall of the cover portion and the tubular body are both cylindrical and the sidewall of the cover portion is concentric to the tubular body. 
     
     
       3. The standpipe of  claim 2 , wherein the gap is an annular recess defined between the bottom edge of the sidewall of the cover portion and the open top end of the tubular body. 
     
     
       4. The standpipe of  claim 1 , wherein the open bottom end of the tubular body is defined by a frustoconical sidewall. 
     
     
       5. A standpipe for a warewashing machine, the warewashing machine including a hot water tank defining a drain aperture, the standpipe comprising:
 an elongated body having a first open end defining a first edge and a second open end opposite the first open end, wherein the second open end is configured to be removably seated in the drain aperture of the hot water tank of the warewashing machine; 
 a cover portion coupled with the elongated body and disposed over the first open end, the cover portion defining a base wall and a sidewall extending about the base wall, the sidewall defining a cover portion open end opposite the base wall; 
 wherein the first edge of the first open end of the elongated body is located interior of the sidewall of the cover portion and a gap is defined between the first open end and the sidewall; 
 wherein the gap is in fluid communication with the cover portion open end such that fluid exterior of the cover portion can flow through the cover portion open end, through the gap, and into the first open end of the elongated body. 
 
     
     
       6. The standpipe of  claim 5 , wherein the base wall of the cover portion is fixed to the first edge of the of the elongated body by a plurality of posts, the plurality of posts defining a plurality of drain openings therebetween. 
     
     
       7. The standpipe of  claim 5 , wherein the first open end of the elongated body is concentric with the sidewall of the cover portion. 
     
     
       8. The standpipe of  claim 5 , wherein the gap is annular in shape. 
     
     
       9. The standpipe of  claim 5 , wherein, when the second open end is removably seated in the drain aperture of the hot water tank of the warewashing machine and the hot water tank is filled with water, a surface level of the water is above the sidewall open end and below the first open end of the elongated body. 
     
     
       10. A standpipe for a warewashing machine, the warewashing machine including a hot water tank defining a drain aperture, the standpipe comprising:
 a tubular elongated body having a proximal end configured for engagement with the drain aperture of the water tank of the warewashing machine and a distal end opposite the proximal end, wherein the proximal end defines a proximal end opening that is in fluid communication with a distal end opening located at the distal end; 
 a cover located at the distal end of the elongated body, the cover comprising a first wall and a sidewall depending from a periphery of the first wall, wherein the first wall is coupled with the distal end of the elongated body and wherein the sidewall defines cover opening opposite the first wall; 
 wherein the cover opening is located proximal of the distal end opening and wherein the sidewall is spaced apart from the distal end of the elongated body to define a fluid path extending from an exterior of the cover, between the distal end of the elongated body and the sidewall, through the distal end opening, and to the proximal end opening. 
 
     
     
       11. The standpipe of  claim 10 , wherein the first wall is circular in shape. 
     
     
       12. The standpipe of  claim 10 , wherein when the proximal end is engaged with the drain aperture of the hot water tank of the warewashing machine and the hot water tank is filled with water, the distal end opening is above a surface level of the water and the cover opening is below a surface level of the water. 
     
     
       13. The standpipe of  claim 10 , further comprising a plurality of drain openings disposed between the first wall and the distal end of the elongated body. 
     
     
       14. The standpipe of  claim 10 , wherein the cover further comprises a second wall opposite the first wall and distal thereof, and wherein the sidewall extends between the first wall and the second wall. 
     
     
       15. The standpipe of  claim 10 , wherein the cover is configured to engage a lever or handle operable to raise the elongated body relative to the drain aperture of the hot water tank.
